Alternative schooling has a long history. However, defining alternative schooling is difficult because it necessitates an answer to the question: “alternative to what?” It suggests that there is an accepted schooling archetype from which to differentiate. However, just what that model might be is likely to vary over time and place. In one perspective, alternative schools challenge what Tyack and Tobin, in 1994, referred to as the traditional grammar of schooling as it pertains to conventional forms of schooling developed in Western societies since the Industrial Revolution. Alternative schools challenge the taken-for-granted grammar of schooling variously through their organization, governance structures, curriculum, pedagogy, type of students, and/or particular philosophy. Certain types of alternative schools, including democratic schools, developmental and holistic alternative schools (e.g., Montessori and Waldorf/Steiner), and flexi schools, might offer lessons to the educational mainstream on how to be more inclusive and socially just. However, there are also ways in which they can work against such principles.
